simple backup

This is a simple network backup system using rsync and hard links.
The work is done by the backup.sh script.  There are crontabs to
run the backup every hour, day, or month.  There is a logrotate
snippet to ensure that the log files are managed.  There are bits
for configuring logwatch so you can find out about what is happening.
